Rocky, according to press notes, "brings to life the iconic and inspiring story of struggling small time Philly boxer, Rocky Balboa, who gets a once-in-a-lifetime shot to go the distance against heavyweight champ Apollo Creed. Both an adrenaline-infused spectacle and a surprising story of blossoming romance between two lonely outsiders, Rocky is a heart-stopping and viscerally theatrical new musical for everyone brave enough to follow their dream."
